The shiny steel
ring to which you refer is the outer race
for the prop shaft bearing. Normally it is pressed out of the housing using a press and a special tool from the rear (oil seal) side. If you donít have the special tool you can support the housing on a couple of pieces of wood
and tap the race
out carefully with a brass drift and a hammer. Behind the bearing race there will be one or two shims. The arrow in photo
3 is pointing to the shims. Save the shims as they have to go back upon reassembly.
Once the bearing race is removed the oil seals
are easy to tap out of the housing, and also easy to tap in the new seals
. Remember that the rear seal spring faces the water
and the front seal spring faces the oil. After replacing the seals put the shims into the housing and press the bearing race back into the housing. Be sure the race goes all the way to the bottom of the recess and presses against the shims.
Replace the two ďOĒ rings on the outside of the housing with new, lubricate the new oil seals with oil or grease and reassemble the whole thing. Put a little silicon or gasket
sealer on the mating surface of the bearing carrier and the leg to keep water
out of there, and donít forget to grease the splines on the propshaft so it comes apart easy the next time.
